This intake is ported by Chuy's Porting and Performance and ships directly from Chuy once complete (Estimated 3-5 business day lead time).
TUNING WILL BE REQUIRED. L86 throttle body is required on L83 engines (the OEM L83 throttle body is NOT compatible with the L86 intake).
An excellent upgrade for factory L83 (5.3L) 2014+ GM trucks. This intake manifold and throttle body package is ported by Chuy's Porting and Performance. Typical gains are 20-25 RWHP depending on tuning.
Kit Includes:
- GM L86 Intake Manifold (Ported)
- GM L86 Throttle Body (Ported)
- GM L86 PCV Hose Assembly
- GM L86 Throttle Body Gasket
NOTE: Intake gaskets must be reused from original intake, please be careful when removing. NOT compatible with factory L83 throttle body to inlet tube coupler. Most aftermarket cold air intake packages will include the larger 6.2L coupler.
NOTE: 2024 and later trucks use a different pinout on the throttle body and cannot use the ported L86 throttle body in this package. If you have a 2024 or newer, please shoot us an email so we can get you set up with a custom bundle.
